Linux Security refers to the set of practices, tools, and configurations used to protect Linux operating systems from unauthorized access, vulnerabilities, malware, and other cyber threats. It involves managing user permissions, configuring firewalls, applying security patches, and monitoring system activity. Linux security professionals also implement measures such as SELinux, AppArmor, and intrusion detection systems to safeguard data and maintain system integrity.
